[Cytochemical study of lymphocyte nucleoproteins in rheumatoid arthritis patients]. / Tsitokhimichno izsledvane na nukleoproteini v limfotsitite na bolni s revmatoiden artrit.

The purpose of the study is to investigate and juxtapose the cytochemical characteristics of ribonucleoproteins (RNP) and deoxyribonucleoproteins (DNP) in the lymphocytes of patients with rheumatoid arthritis (RA), of healthy lymphocytes and lymphocytes blast-transformed by phytohemagglutinins. Significant differences in the staining of lymphocytes for nucleoproteins were established in all 54 patients with RA studied. The unidirectional changes in the morphological form of the staining for RNP and DNP in blast-transformed lymphocytes and lymphocytes in RA is, most likely, in connection with the transition of the latter into active functional state and their participation in the forming of the immune inflammation. No significant difference was established in the dependence on the RA form--sero-positive or sero-negative. Regardless of the negative serological samples in the second form, there were some changes in the lymphocytes--carriers of immune reactions in organism.

[Cytochemical study of leukocyte cationic proteins in rheumatoid arthritis patients]. / Tsitokhimichno prouchvane na levkotsitnite kationni proteini pri bolni s ravmatoiden artrit.

The markers of granulocyte order non-ferment cation proteins (CP) have pronounced bactericide, vascular-permeable and anticoagulant effect. In connection with the participation of leukocyte ferment and non-ferment systems in the formation of immune inflammations, the cytochemical studies on CP in neutrophil polymorphonuclears in rheumatoid arthritis (RA) are of certain importance. A cytochemical method in confirming CP was applied upon smears of peripheral blood of 54 patients with RA and 90 healthy subjects. The results were presented in a mean cytochemical coefficient according to Astaldi and Verga. A significant reduction of CP was established in the leukocytes of patients with RA regardless of the form - sero-negative or sero-positive. Most likely, immune conditioned changes in leukocyte metabolism were present in both forms which no doubt had an effect on their participation in the protective reactions of organism.
